北京城市园林绿地中的雨水利用

Beijing Urban Green Space of Rainwater Utilization

为更好地促进城市园林绿地的可持续发展,缓解城市水资源短缺与园林绿地灌溉用水之间的矛盾,根据北京地区降雨特点及城市绿地建设现状,提出了下凹式绿地、渗水井、渗水边沟、树皮覆盖、渗透铺装几项雨水利用措施及其在绿地中的实施方法。这些措施可以将雨水最大限度应用到城市绿地,满足园林植物生长的需求,同时可以有效地回补地下水。雨水资源的有效集汇利用,在一定程度上降低了绿地灌溉量,节约水资源。

In order to better promote the urban green space sustainable development,decrease the conflict between the shortage of city water resources and the green space irrigation,according to the characteristics of rainfall in Beijing and the construction status of urban green space,concave-down green space,penetrative-well,infiltrative-groove cortex-cover and penetrative-flagging,a number of rainfall utilization measures are proposed those measures can be applied maximum in urban green space and meet the growing demand for garden plant,at the same time can be recruited groundwater availability.The effective use of rainwater sinks,to a certain extent,reduce the amount of green land irrigation and conserve the water resources.
